JOHN BRAUNXVALDER, OF DAVENPORT, IOWA.

FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 655,599, dated August 7, 1900.

Application filed November 29, 1899. Serial No- 738,717. (No model.)

To all whom it may concern:

Be it known that 1, JOHN BRAUNWALDER, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented a new and Improved Fire-Extinguisher, of which the following is a full, clear, and exact description.

This invention relates to improvements in fire-extinguishers of that class comprising a container for an extinguishing liquid and designed to be broken to discharge the liquid; and the object is to provide a fire-extinguisher of simple construction and having a means actuated by fire to break the container, thus making the device practically automatic.

I will describe a fire-extinguisher embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarcharacters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of a fire-extinguisher embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a bottom view with the cover removed. Fig. 4 is a section on the line 4 4 of Fig. 3. Fig. 5 isa perspective of a cover-holding ring employed. Fig. 6 shows a perspective view of the cover, and Fig. 7 shows the explosive holder detached from the extinguisher.

The device consists of a container 1 for a fireextinguishingliquid. This container consists of glass or other fragile material, and it is here shown as spherical; but it may be otherwise shaped without departing from the spirit of my invention. At the upper side of the container is an eye 2, in which a suspending device may be engaged to support the extinguisher from a ceiling or the like. At the bottom of the container 1 is an interiorlythreaded projection 3, in which is screwed a tube 4, the upper end of which is closed, and this upper portion, which extends to about the center of the container, is enlarged to receive an explosive material-such, for instance, as powder 5. The lower or outer portion of the tube is provided with a chamber 6, in which a fuse 7 is designed to be stored. This fuse is made in the form of a cord and when stored in the chamber 6 is coiled, as indicated in Fig. 8, and supported on a plate 8, which engages with opposite side walls of the chamber. This fuse extends up through the tube 4 and communicates with the powder 5, and at its free end there is a weight 9, which normally rests on a closure or cover 10 for the chamber 6. At opposite sides this closure or cover has perforated lugs 11 to engage between lugs 12 on opposite sides of a ring 13, of metal or other suitable material, which surrounds the lower portion of the tube, as plainly indicated in the drawings The cover is held in place by fusible wires 14, which pass through the lugs 11 and 12.

In operation the extinguisher is designed to be supported from a ceiling or other suitable place, and the fuse-cord 7 should be of sufficient length to reach to the floor. Should a fire occur in the vicinity of the extinguisher, when the heat reaches a su fficiently-high temperature the fusible wires 14 will be melted, allowing thecover 10 to fall, and consequently allowing the weight 9 to draw the fuse-cord down, so that when fire or flame reaches the fuse-cord it will be ignited and burn until it' reaches the powder 5, which upon exploding will shatter the container 1, causing the liquid to be thrown to a considerable distance in all directions and extinguishing the fire.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A fire-extinguisher, comprising a c011- tainer for an extinguishing liquid, a holder for an explosive arranged in the container, a fuse leading into the holder, and a chamber in the holder in which the fuse is normally coiled, substantially as specified.

2. A fire-extinguisher, comprising a container for an extinguishing liquid, a holder for an explosive within said container, a fuse leading into said holder, a chamber in the holder in which the fuse is normally held and a weight on the free end of the fuse, substantially as specified.

3. A fire-extinguisher, comprising a container forliquid, an explosive-holder extended into the container, afuse communicating with the holder, a chamber in the lower portion of said holder and adapted to hold the fuse, a cover for the chamber and fusible wires for holding the cover in at. A fire-extinguisher comprising a container of glass or other similar material-adapted to be suspended, a tube of glass or the like extended into said container and adapted to hold an explosive powder, a fuse extended through said tube and having a weight at its free end, a chamber in the outer end of said tube and within which the fuse may be coiled a cover for the chamber, a ring surrounding [O the outer end of said tube and having perfo- In testimony whereof I have signed my name to this specification in the presence of I 5 two subscribing witnesses.
